Thus, efforts to stop eating sugar or to decrease the amount of sugar
consumption may be very difficult for some individuals. Less well-known
risks of sugar consumption are cancer66 and tuberculosis. 67 The Department
of Agriculture’s 2010 Dietary Guidelines, the Department of Health and
Human Services, and the American Heart association have all advised
Americans to limit their sugar consumption because of the health risks
associated with its excessive intake.

Additional research is needed to determine the level at which sugar
consumption becomes toxic. Dr. Lustig points out that “[a] little is not a
problem, but a lot kills slowly.” 68 While American sugar consumption is a
lot higher than it is in much of the rest of the world, 69 we need controlled
studies to determine at what point sugar consumption leads to fatty liver,
insulin resistance and metabolic syndrome. “In . . . laboratory rats and
mice, it’s clear that if the fructose hits the liver in sufficient quantity and
with sufficient speed, the liver will convert much of it to fat,” 70 leading to
insulin resistance and metabolic syndrome. 71

One of the reasons why sugar consumption contributes to the foregoing
diseases is that in many ways, we metabolize sugar the same way we
metabolize alcohol. Fructose is a “chronic toxin” rather than an acute toxin
like ethanol (alcohol), in that it does not cause drunkenness; rather, the
harmful effects of sugar are seen over time. 72 Fructose, however, is
